• Fixed Brightness filter with a reduced level is different when there is clip with transparency above it (broke in v25.12).
• Fixed a crash in the scrub-bar on a very long playlist.
• Fixed app not responding while enqueuing very many proxy jobs.
• Fixed Previous/Next in Subtitles may be unreadable on some themes and OS.
• Changed bulk proxy generation (when you switch Settings > Proxy > Use Proxy ON) to update clips.
  (Previously, you had to turn proxy mode off and back on again to start using the proxies. That requires reloading the project each time, which was a real drag.)
• Changed Timeline > Add Generator and New Generator > Add To Timeline to not seek.
  This leaves the playhead over the clip it just added to facilitate preview and reduce steps.
• Added converting a project between GPU & CPU.
• Improved the appearance of outline on many of the text filters.
• Increased the maximum resolution in Video Mode and Export to 8640 for 8K VR180 video.
• Added the Blend Mode filter and track option for the Linear 10-bit GPU/CPU processing mode.
• Added Settings > Preview Scaling > Use Hardware Decoder.
  • It defaults ON.
  • Obviously, it only supports codecs that your hardware supports, but it automatically falls back to software decoding.
  • It requires VA-API on Linux, uses Media Foundation on Windows, and uses Video Toolbox on macOS.
  • Do not expect to be blown away by speediness unless perhaps you are using Linear 10-bit CPU processing mode.
  • It does not seem to help much with seeking and scrubbing; proxies are still key for that.
  • It does reduce CPU usage, which is important to reduce battery usage or keep the system cooler, for example, if it is on your lap.
  • It is not integrated with the GPU processing mode by using so-called 0-copy.
  • There is still considerable overhead to transfer uncompressed video between CPU & GPU RAM, which is why this feature is coupled with preview scaling or 1080p-60fps or less video sources. Things higher than that are actually slower to transfer than software decode for most systems.
• Added Export > Codec > Use hardware decoder.
  • It defaults OFF because it often increases the export time.
  • Like preview, it too can reduce CPU usage, and that may be a benefit.
    (9 out of 10 software engineers recommend that you do not export your video on your lap!)
  • Feel free to test it and make your own conclusion about what works best for you on your system.
  • The option is sticky, meaning it is remembered between sessions and projects.
• Added Help > What's This? to the menu and toolbar for contextual help.
• Upgraded Qt to version 6.10.1 on Windows.
